Reactive flame‑retardant chemistry will enable FR groups to be grafted directly onto polypropylene chains during polymerization or extrusion. For example, maleic anhydride–grafted polypropylene (MAPP) can be reacted with amine‑functionalized phosphinates to yield a covalently bound FR system. This approach virtually eliminates migration, leaching, and recycling interference. Large‑scale reactive extrusion platforms are already being tested by compounding leaders.
